Wow, that's pretty obscure. I wonder if the test should be factored out
into line_is_no_newline_at_end_of_file() (or surely there is some more
sensible name), and used by both apply and patch-id. Along with a nice
comment (which I see apply already has) describing what in the world the
magic number 12 means.
